There’s nothing written in stone somewhere, nor any law of physics that says emergencies are always temporary. Sorry to deliver this bad news but emergencies can be ongoing and seemingly permanent and perpetual.
Especially if you do nothing to solve the problems causing the ongoing disaster.
The doomsday clock has been close to midnight for my whole life and I’m not young. The climate emergency is very likely going to exist for centuries now — if humans are even around to use language to describe the situation.
You don’t stop going to the toilet because you’re done with that and shit your pants. So I don’t know why we’d think we can just ignore the ongoing public health situation hoping it’ll magically go away if we say we’re done with emergencies.
